When you add this condition to a transition, the add-on checks the Status of the current issue's linked issues. If the linked issues of the specified issue link type and issue type respect the conditions specified against selected statuses, then the transition is available to the user. If not, the transition is hidden.
The list of statuses that is displayed under the Statuses field has all the statuses across different workflows. This is because the workflow of an issue and that of its linked issues can be different.
Configure the following:
Issue Link Type (mandatory): Select the issue link type that links the current issue to the linked issues to check the specified condition against. Leave "Any (default option)" for no restrictions.
Mode (mandatory): Select one of the following conditions the linked issue(s) must satisfy for the transition to be enabled:
All issues must be in the selected statuses below (default option)
At least one issue must be in one of the selected statuses below
No issue must be in one of the selected statuses below
At least one issue must not be in one of the selected statuses below
Issue Type (mandatory): Select the issue type of the linked issue(s) to check the specified condition against. Leave "Any (default option)" for no restrictions.
Statuses (mandatory): Select one or more statuses from the available list to check the specified condition against.
A typical use of this workflow condition is to hide the transition on the current issue until all its linked issues are in a specific status. Consider a use where you want to hide the “Close” transition on the parent until all its subtasks are closed. To configure it:
Add the “Linked Issues Status Condition” to the “Close” transition of the workflow
